Between one below and one above (option D) two standard deviations of a normal distribution contain 68% of the data.
According to the Empirical Rule, 99.7% of data seen following a normal distribution falls within three standard deviations of the mean. According to this criteria, 68% of the data falls within one standard deviation, 95% within two standard deviations, and 99.7% within three standard deviations from the mean.
